摘　　要：通过对慈溪市耕地284个土壤样品的分析、测定,按有关土壤环境质量标准进行了评价。结果表明,慈溪市耕地土壤环境质量总体良好,适宜于发展无公害农产品和绿色食品。We investigated the soil quality of arable land in Cixi City,Zhejiang Province.The contents of environmental pollutants in soil were analyzed and evaluation for soil quality were conducted for 3 times,according to environmental quality standard for soil(GB15618-1995),environmental requirements for origin of non-environmental pollution vegetable(GB/T18407.1——2001),and environmental technical terms for green food production area(NY/T391-2000).The results showed the average contents of pollutants in soils were Pb 22.3 mg·kg^(-1),Cr 35.1 mg·kg^(-1),Cd 0.209 mg·kg^(-1),Hg 0.138 mg·kg^(-1),As 6.4 mg·kg^(-1),Cu 23.4 mg·kg^(-1),HCB 0.0045 mg·kg^(-1)、DDT 0.0342 mg·kg^(-1)respectively,and the 8.5% of cultivated soil were polluted by Hg,Cd and DDT.The cause of polluted soil was mainly related to application of pesticide.According to Chinese National Environmental Quality Standard For Soils,the conclusion could be drawn that the quality of coastal saline soils ranked the best,Fluvio-aquic soils ranked the second and Paddy soils ranked the third.The results suggest that coastal saline and Fluvio-aquic soils are suitable for non-environmental polluted agricultural products and green food production.
